because Onion is a plant. Plant cells have a large vacuole in the centre of the cell which push the surrounding organelles and the nucleus towards the periphery. On the contrary, if you observe an animal cell you will find that the nucleus is situated right at the center because the vacuole is small comparatively and does not occupy a large space at the center.
Cheek cells are only found in animals, whereas onion cells are found in platns, particularly onion cells. Cheek cells, being animal cells, do not contain a cell wall as onion cells do becasue cell walls are found only in plant cells for structure and rigidness. Onion cells, unlike most plant cells, do not have chlorplasts becasue it does not need sunlight for photosynthesis as other plants do. Being grown underground, it receives nutrients directly from the soil, so chloraplasts are not evident. This is also why onions are never green, since chloroplasts contain chlorpohyll, a pigment which gives plants its green color. Basically, cheek cells are found in animals, and onion cells are found in plants.

Oh, dude, it's like this - in adipose tissue, the nucleus gets squished to the side because the fat cells are just so full of, well, fat. It's like trying to fit into skinny jeans after a big meal - there's just no room for the nucleus to hang out in the middle. So, it gets pushed to the side, chilling there while the fat cell does its thing.
The outside layer of the animal cell is the cell membrane.
The Nucleolus is a 'nuclear organelle' inside of the eukaryotic Cell's nucleus. It's primary role is to synthesize messenger Rna which is rapidly exported, via the Nuclear Pores, to the nearly situated Ribosome peppered Rough Endoplasmic Reticulum.The nucleolus(plural nucleoli) is a non-membrane bound structure and is the centre of the cell. It is composed of proteins and nucleic acids found within the nucleus of eukaryotic cells. Its function is to transcribe ribosomal RNA(r RNA) and assemble it within the cell.
The edge of a cheek cell is irregular and jagged, while the edge of an onion cell is more uniform and rectangular. Additionally, the cheek cell has a softer and more flexible edge due to the absence of a cell wall, whereas the onion cell has a rigid cell wall that gives it a structured shape.
The nucleus is not always in the center of the cell. It will be a big dark spot somewhere in the middle of all of the cytoplasm (cytosol). You probably won't find it near the edge of a cell because that might be a dangerous place for the nucleus to be.
It is not always in the center of the cell. No more than if the endoplasmic reticulum is found there. In some cell types it is found toward the edge. It may be due to what is actually in the cell.

The nucleus is typically located near the edge of the cell to facilitate efficient communication between the nucleus and other cell structures. This positioning allows for quicker transport of genetic information to the cytoplasm for protein synthesis and other cellular processes. Additionally, it may offer protection to the nucleus by keeping it away from potential mechanical stress in the cell's interior.
The plant cell has a cell wall outside the cell membrane which gives it a regular shape, unlike animal cells. Inside the plant cell, there is a large fluid filled sac called the vacuole which also helps to maintain the cell's shape and which takes up most of the space that in an animal cell is filled up by cytoplasm. In the little space remaining between the vacuole and the cell membrane, there is the cytoplasm, where the nucleus is found. So the nucleus in a plant cell is found at the edge in the cytoplasm close to the cell membrane!!
The cell nucleus acts like the brain of the cell. It helps control eating, movement, and reproduction. If it happens in a cell, chances are the nucleus knows about it. The nucleus is not always in the center of the cell. It will be a big dark spot somewhere in the middle of all of the cytoplasm (cytosol). You probably won't find it near the edge of a cell because that might be a dangerous place for the nucleus to be. If you don't remember, the cytoplasm is the fluid that fills cells.
Cell membrane
The nucleus of an elodea cell is suspended in the cytoplasm within the cell wall. When the plant cell is well hydrated, the central vacuole swells with water and pushes the nucleus and chloroplasts toward the outer edge of the cell. In a poorly hydrated cell, the nucleus may be located any where within the cell.
